It depends. One way to look at it is to see that looking at the code
helps you not to be confused my faulty or missing documentation.
Also, do not mix up Squeak with Smalltalk. There are other Smalltalk
dialects which are much better documented.

I think the GUI part of Squeak is not documented very well, period.

There probably are.

What else can you do? Even for Java, you have to go through all the
Javadocs, first to find which Class suits your needs and then which
method is the correct one to use.
Basically, there should be a useful class comment for every class which
explains how to use what class for what.

How is that not useful? If everything is an object and everything is
done via messages, then everything has to happen in methods.
Perhaps you have not completely digested this fact.
I think what is missing in Squeak is the old public/private view that
Envy allowed: It did not hinder a programmer from using a private
method, but at least it showed which ones you should use, the public ones.

Very likely, not.
